Product Description
7 Axis Robot Tandem Stamping Line
For a 7-Axis Robot Tandem Stamping Line, the "7th Axis" typically refers to a High-Speed Linear Transfer Rail or a Servo-Driven Overhead Gantry. This additional degree of freedom transforms a standard robotic cell into a long-reach, high-mobility system capable of servicing large distances between heavy-duty presses.
Zhejiang Qicheng Intelligent Technology specializes in 7-axis integration, allowing ABB robots to "glide" between stations, which significantly reduces the number of robots required for a tandem line while maintaining a high Strokes Per Minute (SPM) rate.
Extended-Reach Automation by Zhejiang Qicheng Intelligent Technology
In large-scale automotive and industrial stamping, the distance between 2000T+ presses often exceeds the natural reach of a standard 6-axis robot. Zhejiang Qicheng Intelligent Technology solves this spatial challenge by mounting ABB IRB 6700/7600 robots on a synchronized 7th-Axis Linear Rail. This configuration allows the robot to pick a part from Press A, travel laterally at speeds up to 5m/s, and place it into Press B with sub-millimeter precision, effectively bridging the gap in a single, fluid motion.
7-Axis Performance & Mobility Matrix
The 7th axis provides a "Travel Stroke" that expands the robot's work envelope from a fixed circle to an elongated corridor.
| Technical Metric | Fixed 6-Axis Tandem | Qicheng 7-Axis Integrated Line |
|---|---|---|
| Horizontal Reach | 2.5m - 3.5m | Unlimited (Modular Rail Lengths) |
| Transfer Speed | Static Pivot | Up to 5.0 m/s (Linear Travel) |
| Positioning Accuracy | ±0.05mm | ±0.08mm (Rail-Compensated) |
| Robot Density | 1 Robot per Gap | 1 Robot can service 2-3 Stations |
| Facility Flexibility | Fixed Station Layout | Adaptive to Variable Press Spacing |
Technical Pillars of 7-Axis Integration
- Servo-Synchronized Linear Motion: The 7th axis is treated as an integrated "External Axis" within the ABB controller. This means the linear travel is mathematically linked to the 6-axis arm's kinematics. As the robot travels down the rail, the arm begins its "Reach-In" motion simultaneously, resulting in a Compound Vector Path that saves critical milliseconds in every cycle.
- High-Torque Rack and Pinion Drive: To move a 500kg+ payload (robot + part) at high speeds, we utilize precision-ground rack and pinion systems with automatic lubrication. The drive motors feature high-resolution encoders that communicate with the ABB OmniCore™ to ensure the robot always knows its absolute position on the track, even after a power cycle.
- Energy-Chain & Cable Management: Operating in a high-vibration stamping environment requires robust utility protection. Our 7th-axis rails feature enclosed, heavy-duty "Energy Chains" that protect power, communication, and pneumatic lines from metal shards, oil mist, and mechanical fatigue over millions of cycles.
- Dynamic Vibration Compensation: A robot moving at high speed on a rail can generate harmonic oscillations. Qicheng's engineers utilize Active Vibration Suppression software to neutralize these forces. The controller "pre-calculates" the counter-torque needed to keep the Tool Center Point (TCP) perfectly stable during high-deceleration "Place" moves.
Key System Highlights
- Multi-Robot Rail Sharing: For ultra-long lines, two or more robots can share a single 7th-axis rail. Our Collision Avoidance Logic ensures they work in tandem without interference, maximizing the utility of the floor space.
- Automated Rail Maintenance: Integrated sensors monitor the friction levels and thermal signatures of the rail bearings, providing predictive alerts to the SAS Intelligent Cloud before any mechanical wear affects the SPM.
- Modular Rail Construction: Our rails are built in 2-meter or 3-meter segments, allowing the line to be extended or reconfigured if the factory layout changes in the future.
Industry Q&A (7-Axis Strategic Focus)
Q: Does adding a 7th axis slow down the total cycle time?
A: Paradoxically, it often speeds it up for large parts. While the linear move takes time, it allows the robot to enter the die at a more optimal angle and eliminates the need for a secondary "hand-over" robot. For large automotive panels, a 7-axis system can achieve 10-12 SPM across distances that would otherwise be impossible.
Q: How do you ensure the rail stays aligned with the presses over time?
A: We use Heavy-Duty Floor Anchoring and precision leveling jacks. Furthermore, the robot performs a "Zero-Point Calibration" check every shift. It touches a fixed reference pin on the press die; if any deviation is detected (due to floor settling or thermal expansion), the software automatically offsets the coordinate system to maintain accuracy.
Q: Is a 7-axis robot more difficult to program than a standard one?
A: Not with our Unified HMI. The 7th axis is programmed as part of the robot's "Linear Move" command. Operators simply define the "Pick" and "Place" points, and the system automatically calculates the most efficient combination of arm movement and rail travel.
